STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 429,805, dated June 10,1890. Application filed November 11, 1889. Serial No. 329,843. (Nomodel.)

To all whom it may concern.-

Be it known that I, LOUIS BURRI-HALDI, watch-manufacturer, of Bienne, inSwitzerland, have invented a new and useful Improvement in Watches, ofwhich the following is a specification.

The invention consists of a new mechanism for winding up the watch andsetting the hands acted upon by means of a revolving internally-toothedring.

The mechanism described below may be combined with every system ofwatches; but it will be particularly suitable for those watches whichare to be placed in the heads of walking-sticks, umbrellas, whips, &e.,or in armlets.

In the drawings, Figure 1 shows the mechism as it is to be seen afterthe removal of the hands and the dial. Fig. 2 shows the same view afterthe removal of the plate 0 and the wheel F. 'In this figure thehand-setting mechanism is at rest and the winding-up mechanism ready towork. Fig. 3 shows the same view as Fig. 2, but with the hand-settin gready to work and the winding-up at rest. Fig. 4 is a section through XY, and Fig. 5 shows separately and in perspective view the handsettingpusher.

In all the figures the same letters refer to the same pieces.

The ring A is provided with internal teeth A, forming aninternally-toothed ring or circular rack, and it is capable of beingrevolved between the plate B, which is provided with a suitable recess,and the plate 0, which is screwed upon the plate B. Theinternallytoothed ringA may be turned in either direction and the glassbezel D is firmly fixed to such ring A. The plate B may be fixed to thewatch-case by any means whatever. Between the plates O and B are lodgedthe wheels of the winding-up and hand-setting mechanism. Awheel b, whichis fixed to the mainspring-axis, is intended to cause the winding up ofthe watch, while the usual wheels 6, d, and m are intended to move thehands. The rotation of the internally-toothed ring A is transmittedeither to the wheel I) of the winding-up mechanism or to thehand-setting wheel 6 by means of an intermediate wheel F, having itspivot f placed into a slot 0 of the plate 0 and its pivot f" into acorresponding slot 1) of the plate B. A spring t', fixed to the plate B,maintains the wheel F in the position shown in Figs. 1 and '2that is tosay, in the position in which the wheel F engages the Wheel b andproduces the winding up of the mainspring when the internallytoothedring A is turned around from left to right. When the internally-toothedring A is turn ed from right to left, the wheel Fj umps from tooth totooth upon the wheel I), the rotation of the latter being prevented bythe usual click of the Inainspring-axis.

The hand-setting pusher G is formed, as shown in Fig. 5, like a wedge,and it is within a suitable recess or hole in the plate B, and it isretained by a screw passing through the slot g into the plate B. Thewedged end of the pin G bears upon the pivotf of the wheel F, anddisplaces the same when the pusher G is pushed inward, whereby thespringiis bent, as shown in Fig. 3, and the wheel F is put out of gearwith the wheel I) and into gear with the wheel 6.

Having thus described my invention, I claim- In a watch-windingmechanism, the wheel F, having its pivot in slots in the plates B and C,in combination with the springt' at one side of the pivot and thewedge-ended pushpiece G at the other side of the pivot, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresenceof two subscribing witnesses.

LOUIS BURRI-HALDI.
